Turn signals won't blink?

[DSRTRDR]

So I have 2 blue one connects to a blue and red wire that connects to a 15 A on my fuse box, the other connects to a green wire. Which do you want me to test as left at the switch? And I am assuming this is my switch box.

no, your turn signal switch is at the steering column where the lever is

part number is for a "speed marker"

flasher on the left? Can you elaborate?

Cancel post. sorry.

 

[DSRTRDR]

I put the part number 83260-60010 into a Google search and it said "speed marker" - nothing to do with flashing

I don't know offhand what the part number for the flasher relay is, but in my recollection, the relay is flatter and black, and it's higher up in the driver side footwell, at least on my '72

also, if I recall correctly, there is no B/G wire in the turn signal wiring circuit

have you looked at Coolerman's wiring diagram for a '71 ? that should answer it all

here's a link to his site, look for the '71 diagram

I'm going to join in the discussion here w/similar basic symptoms in my '72 FJ55. The right side turn indicators blink correctly, but the left side clicks on and stays on, not blinking. The bulbs all seem OK, I've cleaned the housings and all the other lights function as they should including the hazards etc... - it's just the left side blinkers that don't blink.

I do have some more investigating to do, so I'm not dead in the water just yet. Coolerman's website is most helpful w/circuit descriptions etc...

Hoping to find a solution & thought I'd tag along here in case something applied.

Thanks,
Tom

Now that's an interesting problem. The turn signal switch operates by shorting the "flashing input" to either the left side lights for a left turn or the right side lights for the right turn. (assumes FJ55 switch operates like FJ40).

The four lights are independent of each other and are only "tied together" in the switch by a shorting block. It uses the same input from the flasher and the switch just routed it left or right.

If right is working correctly, then we assume the 12V, 0V, 12V... input to the switch from teh flasher is ok... so why when you short it to the left side do you get what you do?

Obviously a solid 12V is being applied to the left side that's why they are solid. And since both front and rear are coming on together for the left side, we have to assume one of three things. 1. there is either a problem in the switch and the left side is not being shorted correctly to the flashing input (easy to check with a multimeter, 2. the input voltage actually stops flashing when in the left position, but the switch is routing correctly (harder to understand), or 3. there is an unexpected short that is applying a solid 12V when in the left position.

Have you always had this issue, or is it new?

Coolerman is the expert, but talk it thru a little more and maybe we can help.

Another ground issue.

At the front blinkers, the ground is made by the post that the wire slides through, and the 17 MM bolt/washer that hold it to the fender. I cleaned the blinker post and the bottom side of the fender where it makes contact, and wala. I brought it down to metal and that did the trick.

 

[jeffdkid]

issue resolved

Grounding issues at the front blinker lights is common, so after cleaning really good (Sanding / acohol), blinkers worked fine. Need good metal contact on those

 

[jeffdkid]

check all your grounds reallly good.

Try to make sure you have good metal to metal contact ground on the hardware connected to the fenders.

check into the adjustment on the rod to the blinker switch - make sure it has good contact when you switch the lever to either side

Thank you Tim, Jeff & DSRTRDR for the help. I've been sidetracked the past few days installing a rebuilt brake booster and trying to get the tailgate window motor working again, among other things. . .

I am planning to take another look at the blinkers tomorrow.

At the front blinkers, the ground is made by the post that the wire slides through, and the 17 MM bolt/washer that hold it to the fender. I cleaned the blinker post and the bottom side of the fender where it makes contact, and wala. I brought it down to metal and that did the trick.

Jeff - I get the distinct impression that you suggest I check the grounds! That will be the first thing I will do!

Thanks again for the help,
Tom

You guys in this thread, meet these guys in this thread:

https://forum.ih8mud.com/40-55-series-tech/554568-fixed-turn-signal-issue.html

PS The rears could have the same issue. Don't sand, file. Scrape them up really well. Try some dielectric grease to make the connection last longer. It's not a great design, so maybe plan on doing it again sometime. A new battery will help too.

humm got on here to search some stuff for my blinker probem and came across this thread. maybe someone can shed lsome light on my dilemma. I have a 73 harness in a 12/71 fj40 so trying to retain the 71 turnt signal mechanism (6pin plug). the 73 harness also has a 6pin plug but apparently the pins are in diff locations. so basically i think i just need to repin one of the plugs but cant find anything with terminal views. any ideas?

 

[Fast Eddy]

Easy enough to figure out with a multi-meter and a +12v wire over to the battery.

 

[roma042987]

Sheesh yeah guess I could do that. I'm spoiled with modern Honda/acura etm schematics which have connector pinouts, photos, and "how the circuit works" descriptions. Theses archaic things are simple enough but seems like resources are a bit hard to come by.

 

[AlexJet]

Sounds like a resistance issue for me.
When you have bulb burned your rate goes up due to lowering resistance. Slow or no flashing leads to having too high resistance.
I think hazards bypassing this resistance.

 

[Tim71FJ40]

you can find what is shorted to what by the following diagram...

 

[crowbarforge]

I am chasing a similar problem....turn indicators stopped working, both right and left. Hazards flasher work, left, right, front and rear. Starting with easiest and moving on, if the hazards work, does that mean my blinker/flasher is ok and I have a problem somewhere else?

Also lost my windshield wipers. I suspect some switch issues here...wish I had a garage to work in.

 

[thecrazygreek]

You have two fixes possible. One, use higher watt bulbs to provide enough resistance for the flasher to flash. Remember, when hazards work theres 4 corners pulling juice, when u use signals, theres half the juice, which in your case is not enough to get the flashers to flash.
To bypass this use an electronic flasher that doesnt give a hoot about resistance and just flashes regardless. Plus all the info regarding having good grounds is solid advice no matter...

Hope that all made sense.
